I just don't know all the steps I need to take in Flash to accomplish this.

I tried doing the following but it hasn't worked.

Created new Flash file called button_popup.fla
Created a button and called it popup_button
Right clicked on popup_button and went into Actions
In Actions I added the following:
--------------------------------------------------------------------------------
button.onRelease = function() {
getURL("JavaScript:window.open('http://www.javascript-coder.com','mywindow','location=1,status=1,scrollbars=1,width=100,height=100');");
}
--------------------------------------------------------------------------------
When I used the Check syntax I got the following error:
--------------------------------------------------------------------------------
**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 1: Statement must appear within on handler
button.onRelease = function() {

So, can someone advise me what I need to do to get a very basic button to open a new browser window on a particular page will resize and remove toolbar, scrollbar and everything else other than the min & close button?

just noticed that on the above it only says button not popup_button but I get the same error on popup_button and I used onRelease because I saw that somewhere else but would rather have onClick but couldn't find that?

ah...sorry I should have mentioned (in this thread) that I can't use Javascript within the HTML page only in the Actionscript...This I was lead to believe is possible??

In the last thread I explained that I can't use any Javascript in the HTML so i posted this one to get help in getting the JS to work in an SWF file onle but it's looking more and more likely that it's not going to be possible??

What's happening is, since you're adding the Actionscript to the actions pane of the button (not the layer), you need to use different syntax when assigning onRelease events. Also, I believe in your initial question, you called the button "popup_button".
Try this:

Not sure I'm doing the right thing because I copied the code you posted but when I click the button nothing happens?

I created a new flash file called popupButton.fla
Created a small oblong then converted this to a symbol / button called popup_button
Then right clicked this button and selected Actions
In the blank actions window, I copied the code you posted
Then I published the fla file and opened the HTML file that was outputted

also after taking a look at the HTML Code in the page that Flash generates, it puts the Javascript in there which as I keep explaining isn't going to work........?

I'm sorry but if I can't get an SWF button/file to open a new browser window without having to have Javascript in the HTML it's a waste of time, and points. The whole point was to get around having Javascript in the HTML page....
